The expression patterns of prognostic risk genes and their correlation with OS in patients with LUAD. A The Kaplan-Meier plot depicts the relationship between the expression levels of S100P, GPX2, PRC2, ARNTL2, and RGS20 and OS in LUAD patients. B The expression patterns of S100P, GPX2, PRC2, ARNTL2, and RGS20 in LUAD and normal samples are presented based on data from the GEPIA database. C RT-qPCR analysis of S100P, GPX2, PRC2, ARNTL2, and RGS20 was conducted using matched clinical tissues (n = 8). D Immunohistochemical analysis of S100P, GPX2, PRC2, ARNTL2, and RGS20 was performed on LUAD and normal tissue samples sourced from the Human Protein Atlas (HPA) database. HR, hazard ratio; OS, overall survival; LUAD, lung adenocarcinoma. Statistical significance is indicated as *P < 0.05; **P < 0.01
